Long story short, I asked the same question last year and got a photo-essay reply. The hike kicked azz, if you like hiking your sack off for the sheer joy of it. The guy who responded to me never caught any fish, as (I am told) the trail comes in to the EAST side of the lake, and during the summer months the fish are not present in any great numbers in the east end. I was told by the guy who should know that only EARLY EARLY (late May, early June) in the season are the fish present in good numbers in the east end of the lake accessible by trail.
I'd say go for it. The hike is something worth doing by itself. I'll do it someday.
But I'd be wary if the bridge is out. Early June is probably not the best time to be attempting to ford the river
